POWER CONDENSER WASHER.

Application filed April 15, 1925.

This invention relates to improvements in power condenser washers and one object is to provide a device of this class that will direct a stream of water, under pressure, into the comlenser tubes, the water hose being adapted to travel in a circle and all of the tubes in the circumference of such circle being washed consecutively. A further object is to provide a washer than can be used while the condenser is in operation. A still further object is to provide a washer that is very eliicient in use. and that will clean all of the tubes in the condenser.

lVith the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter." fully described, pointed out in the appended claims and illustrated in the accompanying drawing which forms a part of this application and in which- Fig. 1 is a view of the washer illustrating its application to a condenser.

Fig. 2 is a vfragmentary view of the washer taken on line 22 of Fig. 1.

Fig. 3 is a sectional view taken on line 33 of Fig. 1.

Fig. 4 is a section taken on line 4-4 of Fig. 1.

Like reference characters denote corresponding parts throughout the several views.

One of the serious disadvantages of the known condenser washers is their inability to direct a stream of water into the condenser tube in the plane of the tube. Water directed into the tubes at an angle loses much of its effectiveness through contact with the tube body and consequent loss of force. The present invention is without this disadvantage. The water delivery nozzle travels in a circle and all of the tubes lying in the circumference of that circle are washed. By automatic means the diameter of this circle is changed after each complete revolution so that another circle of tubes is then washed and in this manner all, or practically all of the tubes are reached and washed automatically. Any tube or tubes that are not reached in this manner may be washed singly with the machine or otherwise.

The reference numeral 1 denotes the tube sheet of a condenser and 2 the tubes. The water box 3 has secured thereto the arm 1 through one end of which the rotary shaft 5 extends that is tapped into the water box Serial No. 23,279.

3, said shaft being formed throughout a substantial portion of .its length with the bore (3 thus providing water feed means from said water box. Secured to the arm 1 and perforated to receive the shaft 5 is the packing gland 7 which is circular in formation and provided with peripheral teeth 8. Bolted to the outer and solid end of the shaft 5 by the heads 9 is the shaft extension 10 formed with the offset 11 whereby said shaft extension is disposed ofl' center with relation to the shaft 5.

The forward end of the shaft extension 10 is disposed at right angles to the body portion and has bolted thereto one end of the post 12 that carries the bearings 13, 14, 15, the bearing 13 being provided with sprockets 1(5 and 17, the bearing 15 with a sprocket 18 and the bearing lat with a sprocket 19. The sprockets 17 and 19 are connected by the sprocket chain 20 and the sprockets 16 and 18 by the sprocket chain 21. Secured to the chain 21 by plates 22 is the nozzle carrier 23 that carries the nozzle 24 that leads from the elbow 25 coupled to the hose 26 that leads into the bore 6 in the shaft 5.

A feed shaft 27 driven by the sprocket 19 is operatively supported in bearings arranged in the post 12 and in a bracket 28 carried by and rotating with the shaft 5, said feed shaft being provided at one end with the pinion 29 adapted for intermittent engagement with the teeth 8 of the gland 7 as the shaft 5 and connections rotates. A drive shaft 30 operated from any ower source is arranged in bearings in a post 31 carried by the said arm 1, said drive shaft having a worm 32 at one end thereof in mesh with the worm gear 33 of shaft 5.

In operation the water, under pressure leaves the water box through the bore 6 in shaft 5, through the hose 26, elbow 25 and nozzle 2 1 and is directed into the tubes 2. The shaft 5 is disposed in the plane of the center of the tube sheet and the nozzle is slowly rotated about the shaft 5 by revolution of the same. The post 12 is rotated oif center and the nozzle thus caused to describe a circle about the shaft 5 as a center. As the pinion 29 comes in contact with the teeth 8 of the gland 7 it oscillates or rotates the feed shaft 27 thus causing the chain 21 to raise or lower the nozzle a dis tance equal to the space between the centers of two successive tubes 2 so that a larger or smaller circle of tubes is washed after each adjustment of the hose by the feed shaft and connections. The pinion 29 will pass entirely about the gland 7 without rotation until it meshes with the teeth 8 thereof which engagement causes it to rotate.

hat is claimed is 2-- 1. In a power condenser washer, a rotary water-feed shaft, a carrier supported at one end of said shaft and rotatable thereabout, mechanism for varying the distance of said carrier from the axis of rotation of the shaft, mechanism operative on rotation of the shaft for actuating the first mentioned mechanism, and a water hose communicating with said shaft and supported at its discharge end by said carrier.

'2.
